| Abstract: | Considering the contributions of miler shell and elastic - plastic deformation to temperature field and stree field, a two - dimension dynamic thermal- mechanical coupled computation model was estabfished. Fortran language was used to make better use of MARC to simulate the complex boundary condition and thermal contact condition. The distribution of temperature field and stress field in continuous cast rolling can be acquired by Lagrangian Method. The effect of various rolling speeds on the temperature field and stree field and cast rolled stocks were analyzed and compared. |
